The heat dissipation problem of new energy vehicles has always been one of the focus of attention, and the traditional heat dissipation technology has been unable to meet the heat dissipation problem of today's lithium batteries. Today we will talk to you about why thermal conductive silicone film can be recognized by new energy vehicles to solve the heat dissipation problem.

Thermally conductive silicone film, from the very beginning of its existence, has decided to be extraordinary. So what are the advantages of thermal conductive silicone film?

A, bridging the process difference, reduce the heat sink and thermal structure of the process difference requirements, thermal conductive silicone film thickness, softness can be adjusted according to the design of different, so in the thermal conductivity channel can be bridged in the thermal structure and chip size difference, reduce the structure of the design of the contact surface of the heat sink pieces of production requirements, especially for flatness, roughness of the work difference. If you improve the processing accuracy of the thermal conductive material contact parts will greatly enhance the cost of the product, so the thermal conductive silicone film can fully increase the contact area of the heat sink and heat sink parts, reducing the production costs of the heat sink and contact parts. In addition to the most widely used thermal conductive silicone film PC industry, the new thermal solution for products is now to remove the traditional heat sink, the structure and heat sink unified into a thermal structure. In the PCB layout of the heat sink chip layout in the back, or in the front layout, in the need to dissipate heat around the chip open heat sink holes, the heat through the copper foil and other conductive to the back of the PCB, and then through the thermal conductive silicon film filling to establish a thermal channel to the PCB below or side of the thermal structure (metal bracket, metal shell), the overall thermal structure of the optimization. This not only greatly reduces the cost of the entire thermal solution of the product, but also minimizes the size and portability of the product.

Second, the range of thermal conductivity and stability, thermal conductive silicone film in the thermal conductivity of a broader range of options, its products can be from 0.8w/k.m ----3.0w/k.m or even above, and stable performance, long-term reliability of use. Compared with the thermal conductive double-sided adhesive, the highest thermal conductivity is not more than 1.0w/k-m, and the thermal conductivity is poor. Compared with the thermal conductive silicone film, thermal conductive silicone grease has the form of room temperature curing, which is easy to produce surface drying and cracking or unstable performance at high temperature, and easy to volatilize and flow, and the thermal conductivity will gradually decline, which is not conducive to long-term reliable system operation.

Third, the advantages of shock absorption, thermal conductive silicone film silicone carrier determines its good elasticity and compression ratio, so as to achieve the effect of shock absorption, if then adjust the density and softness more can produce a good absorption of low-frequency electromagnetic noise. Relative to the use of thermally conductive silicone grease and thermally conductive double-sided adhesive determines that other thermally conductive materials do not have a damping and sound absorption effect.

(IV.) Electromagnetic compatibility (EMC), insulation performance thermal conductive silicone film has good protection for EMC because of its own material characteristics of insulation and thermal conductivity, and it is not easy to be pierced and torn or broken under pressure because of the silicone material, so the EMC reliability is better. Due to the limitation of the material itself, the thermal conductive double-sided adhesive has low EMC protection performance and often cannot meet the customer's demand, so it can only be used when the chip itself has been insulated or the chip surface has been protected from EMC. Generally, it can only be used when the chip itself has been insulated or the chip surface has been protected from EMC.

V. Reusable and convenient. Thermally conductive silicone film is a stable solid state, the strength of the adhesive being optional, easy to disassemble and reusable. Once the thermal conductive double-sided adhesive is used, it is not easy to disassemble, there is a risk of damage to the chip and surrounding devices, not easy to disassemble thoroughly. When scraping thoroughly, it will scratch the surface of the chip and bring dust, oil and other disturbing factors when applying, which is not conducive to thermal conductivity and reliable protection. Thermal conductive silicone grease must be applied carefully, and it is not easy to apply the average thorough, especially in the replacement of the thermal conductive media test, which will have an impact on the reliability of the test data, thus affecting the judgment of engineers.

Thermal conductive silicone film has an important role to play not only in the new energy field, but also in other fields such as LED industry, power supply industry, heat dissipation of computer COU, various electronic industries, home appliances, etc. Today, in the era of 5G, thermal conductive silicone film will once again bloom its brilliance and dedicate itself to the heat dissipation of various 5G products.。
